What is modding in Minecraft?

Modding in Minecraft allows users to customize many features of the game through:

  • Data Manipulation
  • Code Manipulation
  • Scripting

Java is the most common programming language used in Minecraft mods, but you can also expect to see JavaScript within add-ons for Bedrock edition. The tag should be used when you have a question or problem related to creating and programming a Minecraft mod.

Note: Mods are NOT the same as plugins. See this post to learn more about the difference.

Resources

There are plenty of resources available for modding and customizing Minecraft, regardless of the edition of the title you're playing.
